Point Load on CJP Fillet Weld formulas

  • Complete Joint Penetration  -  Weld completely fills the gap between the two pieces.

\( \sigma \;=\;   6 \; F_a \; H \;/\;  L \; t^2  \) 

\( \tau  \;=\;  F_a \;/\;  L \; t  \)
Symbol English Metric
\( \sigma \) (Greek symbol sigma) = Weld Stress \(lbf\;/\;in^2\) \(Pa\)
\( \tau \) (Greak symbol tau) = Shear Stress \(lbf\;/\;in^2\) \(Pa\)
\( F_a \) = Total Applied Force \( lbf \) \(N\)
\( H \) = Height of Lever Arm \( in \) \( mm \)
\( L \) = Weld Length \( in \) \( mm \)
\( t \) = Plate Thickness \( in \) \( mm \)

Bending Moment on CJP Fillet Weld formula

  • Complete Joint Penetration  -  Weld completely fills the gap between the two pieces.
\( \sigma \;=\;  6 \; M \;/\; L \; t^2 \) 
Symbol English Metric
\( \sigma \) (Greek symbol sigma) = Weld Stress \(lbf\;/\;in^2\) \(Pa\)
\( F_a \) = Total Applied Force \( lbf \) \(N\)
\(\large{ M }\) = Bending Moment \( in \) \( mm \)
\( L \) = Weld Length \( in \) \( mm \)
\( t \) = Plate Thickness \( in \) \( mm \)

Torsion moment on CJP Fillet Weld formula

  • Complete Joint Penetration  -  Weld completely fills the gap between the two pieces.
\( \tau  \;=\;  T \; ( 3 \; L + 1.8 \; t ) \;/\;  L^2 \; t^2  \)
Symbol English Metric
\( \tau \) (Greak symbol tau) = Shear Stress \(lbf\;/\;in^2\) \(Pa\)
\(\large{ T }\) = torque force \( in \) \( mm \)
\( L \) = Weld Length \( in \) \( mm \)
\( t \) = Plate Thickness \( in \) \( mm \)
